It is with thanks to Marco for sharing these pics to our Facebook page, that I have become interested in them, especially the one showing the reg plate, as with this bit of information I was able to learn a little more.All pics that have been found so far are in black & white, but with the power of the web some people have come forward saying they remember these and were yellow, the same as the jeans model, but the rear quarter script replaced with the word wolves in jeans style font, this was presumably to commemorate Wolves winning the league cup in 1974.From the pics we know for sure there were five in existence, ANP 613M clearly visible and all other reg in sequence, in one way or the other. From one viewers recollection these were given away as prizes, but that for now is all we know, so my quest for more information is out to you guys
